I created this unit because a third grade teacher needed a Partial Product Method unit.
It is differentiated with several challenge levels and it's a skill builder with multiplication and addition. I design with the idea of enlarging these as posters or projecting on the board to teach.
My units have many pages because I provide several challenge levels and several options of each challenge level. Students can wok on the same skill together without copying.
ESL, RTI, math centers, homework, etc. Great as assessments.
